for use in floor construction which may be conveniently and completelmanufactured to avoid assembly on the jo toprovide attaching means whichma be conveniently mounted on a stri of vibration insulating materialsuch as elt, and permanently secured thereto before installation in thatposition in which it is ultimately used in a floor construction, and toprovide integral clips on a device of the class described formed toallow insertion through slits in a felt member and to prevent separationof the latter from the device.

Another object of my invention is to provide means .for confining asound deadening member in a fixed location between the superimposedlayers .of flooring in such a manner as to minimize the amount of rigidconnection between said layers.

In the accompanying4 drawing I have shown an embodiment of my inventionin which Fig. 1 is a fragmentaryperspective of a completed sounddeadening element.

Flg. 2 is a transverse section taken .on the line 2 2 of Fig. 1.

Fig. 3 is a section of a floor construction embodying my invention.

In general, my invention embodies an improved sound vibration insulatingmeans comprising a strip of felt having improved stra s permanentlymounted thereon, forinstal ation between a finish layer and a furringstrip of a Hoor. The attaching member comprises a strap having oppositefeet portions substantially in the same plane, and a top section in aspaced, substantially parallel plane. V The feet and top sections areconnected by inclined side portions. Clips integral at one end with. thetop section are cut out of the latter and bent downwardly substantiallperpendicular to the top section. The ree end portions of the cli s areformed to provide a flange which is su stantially arallel to the topsection.

In t e form shown in the drawings, sound resisting layers 1, preferablycomprising felt, are located between a roughl layer of the floor 2 and afurring strip 3 supported thereon. The finish lor top layer 4 of thefloor is supported in turn by the furring strip 3 as shown in Fig. 3.

My improved sound deadening means comprising a felt strip 5, is locatedbetween the top layer 4 of the floor and the furring strip 3 and isfirmly clamped on the top of the furring strip by a strap 6. The strap 6is provided with feet ortions 7 which engage the upper surface o thefelt member 1, and thus avoid a direct rigid connection between theupper and lower layers of the floor.

During the construction of a floor such as is shown in the drawings, itis desirable to have all the elements required, arrive on the scene ofconstruction in as complete a condition as possible in order that timeand labor may b e saved on the job. For this reason it has been foundpractical to permanently and securely attach the straps 6 to the feltstrip with a flange 10 which is substantiall parallel to the topsections 9, as shown in ig. 2. The straps may be conveniently secured tothe felt strip 5 by inserting the clips 7 through slits in the feltmember so as to engage the flange 10 against the lower surface of thefelt member as viewed in the drawing. Any desired number of straps maybe simllarly mounted on the felt member and when the latter is'positioned over a furring strip, the straps together with the feltmember ma be held permanently in place by driving nai s through aertures in the feet of the strap and through the felt layer or layers 1into the bottom layer of the oor 2.

Although but one specific embodiment of this invention has been hereinshown and described, it will be understood that details of theconstruction shown may be altered or omitted without departin from thespirit of this invention as define by the following n claims.

I claim:

1. A ioor comprising a rough underfloor, spaced furring strips thereon,a top finishfioor and elongated sound insulatingsaddles interposedbetween said finish-Hoor and strips, said saddles having mutually-spacedbowed perforate-footed downholding straps attached thereto for anchoringtensionally to the underfloor.

2. In a floor construction comprising a rough layer, a finish layer, andfurring strips therebetween, a sound resisting element between saidrough layer and said fui-ring strips, and vibration insulating meansbetween said finish layer and said furring strips, said insulating meanshaving straps permanently fixed thereto independently of the Hoorconstruction, and feet on said straps for tensionally securing the same,together with said sound resisting element to the rough layer of theflooring so as to embed the top part of said strap in said insulatingmaterial.
